Abstract
An isolated structural Bacillus sp. TB-90 (FERM BP-795) urease gene, which comprises base sequences encoding the amino acid sequences of three subunits of urease. A recombinant DNA comprising Bacillus sp. TB-90 (FERM BP-795) urease gene capable of replicating in Escherichia coli. A process for producing urease, which comprises cultivating Escherichia coli carrying a recombinant DNA comprising Bacillus sp. TB-90 (FERM BP-795) urease gene capable of replicating in Escherichia coli and recovering urease from the culture mixture
